Here's a good brain-buster - name the ten players since World War II to score 140 or more runs in a season (it's been done 12 times in that period, two guys doing it twice). I guarantee you can keep this one going for a good while in a group of reasonably knowledgeable fans - a ten-man list is the right length for this kind of question and none of these guys is truly obscure, although you may need to think about the ballparks they played in to get two of them.
